DC03 tempers and conditions
DC03 is supplied in 3 conditions, soft to hard.
Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Solution annealed | Maximum ductility and lowest yield for the deepest draws; must be formed promptly because the yield point returns and causes stretcher strains. | 175 | 300 | 41 | 90 HB | 11 % IACS |
Electrolytically zinc coated | Choose when a paintable, dimensionally exact zinc layer (2.5–10 µm/side) is needed for indoor corrosion protection without affecting drawability. | 200 | 315 | 37 | 95 HB | 11 % IACS |
DC03EK | Enamelling-quality version with controlled carbon/hydrogen behaviour, used for cookware, water-heater tanks and enamelled panels. | 210 | 320 | 34 | 100 HB | 11 % IACS |

What is DC03?
DC03 (1.0347, SPCD) is a low-carbon cold-rolled sheet steel to the EN 10130 family for cold forming, with better ductility than DC01 and drawing capability between DC01 and DC04. It is supplied as skin-passed or annealed coil and sheet, electro-galvanized (+ZE) and in enamelling quality (EK), at 195 MPa yield, 310 MPa tensile, 38% elongation and 95 HB (55 HRB). Corrosion resistance is essentially nil (score 10), so bare sheet rusts within days and must be coated. Move to DC04 or DC05 when the draw is deeper. DC03 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,490°C (2,714 °F). DC03 has a yield strength of 195 MPa (28.3 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 99% of steel grades. Elongation at break is 38% and the elastic modulus is 210 GPa (30.5 Msi).

Chemical & Environmental3
Corrosion resistance is not recommended (10/100), worse than 86% of steel grades.
Sustainability4
Producing a kilogram of DC03 takes about 28 MJ of energy and emits 2.3 kg of CO₂ — less than 56% of steel grades. Typical recycled content is 25%.
Manufacturability7
DC03's machinability is fair (50/100, worse than 53% of steel grades); weldability excellent (95/100); formability excellent (88/100).

Working with DC03
Is DC03 easy to machine?
Soft and gummy — use sharp positive-rake tools, high speed and coolant to avoid built-up edge and burrs; ideal for punching/blanking rather than turning.
Can DC03 be welded?
Excellent with resistance spot, MAG, laser and brazing; carbon equivalent is very low so no preheat or PWHT is required (remove zinc coating fumes on +ZE).
Can DC03 be formed, bent or molded?
Designed for deep drawing (r90 ≥ 1.3, n90 ≥ 0.18); use non-skin-passed material promptly to avoid stretcher strains and keep draw radii ≥ 5t for cylindrical cups.
DC03 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on DC03?
Always coated: phosphate + cathodic e-coat, powder paint, zinc or Zn-Ni plating, or porcelain enamel on EK quality; bare sheet rusts within days.

DC03 — frequently asked
What is DC03 used for?
DC03 is typically used for appliance housings, brackets, stamped enclosures and automotive inner panels. In short: better drawing than DC01; low-cost forming sheet; enamelling quality available.
What is the yield strength of DC03?
DC03 has a typical yield strength of 195 MPa (28.3 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 99% of steel grades. Strength varies by condition: see the 3 listed tempers.
Is DC03 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 53% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed and coolant to avoid built-up edge and burrs; ideal for punching/blanking rather than turning.
Can DC03 be welded?
Yes — weldability is rated excellent (95/100). Excellent with resistance spot, MAG, laser and brazing; carbon equivalent is very low so no preheat or PWHT is required (remove zinc coating fumes on +ZE).
What surface finishes work on DC03?
Always coated: phosphate + cathodic e-coat, powder paint, zinc or Zn-Ni plating, or porcelain enamel on EK quality; bare sheet rusts within days.

Designed for deep drawing (r90 ≥ 1.3, n90 ≥ 0.18); use non-skin-passed material promptly to avoid stretcher strains and keep draw radii ≥ 5t for cylindrical cups.
What is the maximum service temperature of DC03?
DC03 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does DC03 cost?
DC03 is a budget-cost steel ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
